Torsion-induced seismic response amplification is a major concern for the seismic safety of
a plan-asymmetric building subjected to the earthquake. Particularly, the undesirable …

The problem of earthquake induced torsion in buildings is quite old and although it has
received a lot of attention in the past several decades, it is still open. This is evident not only …

Considering that a comprehensive review of past work in this field is available, this paper
focuses on the description of two recently developed procedures to incorporate the effects of …

Significant dynamic torsional amplifications are known to occur in asymmetrical buildings
when subject to earthquake excitations. The torsional effects are commonly taken into …

The drift demand of plan-asymmetric buildings in low seismicity regions was studied by
employing Incremental Dynamic Analysis to track the influence of torsion. A stepped …

Torsion of many symmetric structures, which were designed based on the seismic codes, is
due to their asymmetricity induced during inelastic behavior. Although the structure was …

Due to earthquakes, many structures suffered extensive damages that were attributed to the
torsional effect caused by mass, stiffness or strength eccentricity. Due to this type of …

Structural engineers often come across buildings, which exhibit certain degrees of plan
asymmetry. It may in fact even exist in a nominally symmetric structure, because of the …

An attempt has been made to explore the general trends in the seismic response of plan‐
asymmetric structures without any restrictions imposed by a particular code. Systems with …

Seismic provisions have utilized design eccentricities to reduce planar irregularities in
lateral stiffness of buildings. In calculating a design eccentricity, the torsional amplification …
